Correct Answer - Option 3 : 6 : 5 : 11
Given:
Investment amount ratio of P, Q and R respectively = 5 : 4 : 10
Investment rates(compounded annually) of P, Q and R = 20%, 25% and 10%
Calculation:
According to the question,
Let the investments amounts of P, Q and R be 5x, 4x and 10x
Amount after 1 year for P = 5x(1.2) = 6x
Amount after 1 year for Q = 4x(1.25) = 5x
Amount after 1 year for R = 10x(1.1) = 11x
∴ Ratio of amounts after 1 year of P, Q and R = 6 : 5 : 11
